I'm not familiar with this variety but I do know there are varieties that do wonderfully well in greenhouses. There are places in the USA, up near the Canadian border, where the season is so short that I'm sure there are growers who use greenhouses. Don't lose hope, choose the strongest plants to keep and go forth with your plan to raise them in your greenhouse anyway. For next year, you could do some research to find other varieties you could grow. Now that you know you can grow them from seed that opens up a lot of choices to you. I'm sure that here at least half of the tomatoes sold in the winter are grown in greenhouses. I'm pretty sure I saw a lot of greenhouse tomato seeeds in the Johnnys seed catalog, and quite a few of them were developed in your country.
